Help with QwtPlot and QwtPlotCurve. Draw Lines.

[webquinty]

Well. after surfing in the net, I have found

setRawData(d_x, d_limit4, PLOT_SIZE);
setBrush(QBrush(Qt::green, Qt::Dense7Pattern));
setCurveType(QwtPlotCurve::Yfx);
setBaseline(5000.0)

setRawData(d_x, d_limit4, PLOT_SIZE);
setBrush(QBrush(Qt::green, Qt::Dense7Pattern));
setCurveType(QwtPlotCurve::Yfx);
setBaseline(5000.0)

To copy to clipboard, switch view to plain text mode 

The efect of this code in my plot is to fill area between baseline and curve, but I do not find any solution to fill area between two curves.
